How long should a commercial fireproof cabinet last?

A commercial-grade UL-rated fireproof cabinet is built for the long haul — 20–30+ years of normal office use is a realistic expectation. The steel exterior, lock mechanism, and drawer suspension wear before the insulation does; the fireproof core itself doesn't degrade under normal conditions unless it's exposed to moisture or physical impact.
